What else can I help you with?
Mammals have a belly button which is the remainder of their attachment to the umbilical chord but do birds reptiles fish etc. have a remainder of their attachment to the yolk sack?
" All placental mammals will have a "belly button" as this is the remainder of the umbilical cord when they were attached to their mother in the womb. It's difficult to see due to mammals having fur or hair. Also...If you think of it....birds and reptiles that come from eggs will have some "form" of a "belly button" as when they are in the egg they are attached to the "yolk sac" via a cord. Maybe you can't see this clearly due to scales and feathers..but I bet if we looked closely enough..you'd find "something" I bags NOT to be the person who wrestles with a croc to find out if reptiles have one!!!" audry o's answer to http://answers.yahoo.com/question/index?qid=20080325032221AAcFeEk
